PEN IWIPER Filed Aug. 25. 1960 INVENT OR 3,114,351 PEN WIPER Glenn E. Wise, 501 13th St. NW., Washington, Di). Filed Aug. 23, 1960, S631. No. 51,350 1 Claim. (Cl. 1201) This invention relates to a pen wiper structure, and, more particularly, to wiper which may be easily attached to the closure cap of an ink bottle, and, after the bottle is empty, may be removed from this cap and reattached to the cap of another ink bottle.

it is always annoying after filling a fountain pen to have to take time to find a rag or tissue, or the like, on whic to wipe the excess ink from the pen. This invention provides a readily accessible reuse-able pen wiper adapted for attachment to an ink bottles cap.

One of the objects of the invention is to provide an economical, reuse-able pen wiper designed for attachment to the cap of a conventional ink bottle.

Another object of the invention is to provide a blotterincluding clip-on pen wiper which is adapted for attachment to the closure of an ink bottle so as to be continually convenient for use.

Other objects will be apparent from the remainder of the specification and from the drawings.

In the drawings which form a part of this invention:

FIGURE 1 is a front elevation showing my invention attached to the screw-on cap on a conventional ink bottle;

FIGURE 2 is a plan View of the structure of FIG- URE 1;

EEGURE 3 is an exploded front elevational view of my invention; and,

FIGURE 4 is an exploded sectional view taken on the line 4-4 of FIGURE 3.

Referring now to the drawings by reference numerals, my pen wiper is composed of two major parts: -a base plate designated generally by 1, and a blotter element designated generally by 2.

The base plate 1, more particularly, includes a thin, metal, or the like, cupped, downwardly concave disk portion 3 designed to interfit with the top convex face of an ink bottle cap of the type employed as a closure on the ink bottle of FIGURES 1 and 2. In the drawings the ink bottle is designated as 4 and the threaded cap is designated generally as 5. The upper convex face of cap 5 is shown in dotted lines at 6 in FIGURE 1. As mentioned previously, this bottle and cap are conventional. Depending from diametrically opposed locations on the periphery of disk portion 3 are integral, resilent tabs '7 and 8. At the lower end of tab '7 is an inwardly bent flange 9, and at the lower end of tab 8 is an inwardly bent flange it The blotter element 2 is circular in plan, but its underside is dished out to form concave face 11 which is dimensioned to rest fully on the upper convex of disk 3. in the upper side of element 2 is formed an elongated groove 12 adapted to receive a portion of the barrel of a writing pen during a wiping operation.

Before my wiper is attached to a bottle cap, blotter element 2 is wastened by means of glue or the like, not shown, atop disk 3.

After parts 1 and 2 are attached together, the invention may be clipped on bottle cap 5. This is accomplished by lowering plate 1, tabs down astraddle cap 5. Then, by spreading tabs '7 and 8 apart slightly, flanges 9 and 1d are made to pass down around the side edge of the caps rim 13. After this tabs 7 and 8 are released, and flanges 9 and engage. under rim 13. Thus, the flanges, in conjunction with the cooperative intergagement of the concave underface of disk 3 and the upper convex face 6 of cap 5, serve to afiix my invention on cap 5.

After all of the ink has been used from a bottle to the 3,ll4,35l Patented Dec. 17, 1863 ice cap of which my Wiper is attached, the wiper may be removed from the bottles cap merely by spreading tabs 7 and 8 apart and lifting the wiper.

Now the wiper may be clipped on the cap of a new, full bottle of ink if a user so desires.

It should be noted from FIGURE 1 that the major portion of the caps vertical Wall remains exposed even with the wiper attached. Thus, a person has no ditliculties twisting the cap on and oil the bottle in the usual manner.

The blotter element 2, since it has a considerable time to dry between uses, will absorb a considerable quantity of ink and will, thus retain its usefulness. although it is used with several successive bottles of ink.

The groove 12-, as previously mentioned, is provided to receive a portion of a pens barrel, which portion may be rotated against the \grooves wall to wipe excess ink from the pen. incidentally, the corners formed by the intersection of groove 12 with the top surf ces of element 2 provide Ehandy locations for removing lint, or the like, from the pen point.

As an alternative method of attaching disk portions 3 to cap 5, I might remove elements '7, 8, 9 and 10 from the disk and coat the underside of disk 13 with a conventional perpetually tacky adhesive whereby disk 3 could be removably aflixed atop cap 5 merely by sticking it on. Or, as a further alternative, disk 3 (without elements 7, 8, 9 and iii) might be magnetized and removably affixed to cap 5 by magnetic attraction if cap 5 were composed of a ferrous magnet-attracting substance.

Other changes might also be made in my illustrated embodiment without departing from the spirit thereof, for example, blotter element 2 could obviously take many diiferent forms.

Having now disclosed my invention, what I claim as new and desire to secure by Letters Patent is:

In combination: a bottle cap having a substantially circular top surface, an annular wall attached to and depending from the periphery of said surface, and a rim forming the lower edge of said wall; a wiper, said wiper including a disk-like base resting on the top of and at least substantially spanning said top surface, resilient tabs affixed to and depending from opposite sides of said base, a flange afixed to and extending downwardly and inwardly from the bottom of each tab with the uppermost surface of each flange engaging the bottom of said rim and with the innermost end of each flange terminating below said rim, whereby said base is constantly urged downwardly upon said surface, a blotter element superimposed on said base, said blotter element including horizontal top portions and a groove between said top portions, said groove having a curved bottom and said groove and said top portions meeting to form angular corners parallel to said groove, and means attaching said element to said base.
